The invention relates to toys of the type employing a spiral rod and aspinning or propeller device mounted onthe spiral rod and given atwisting motion when moved axially of the rod so that when released fromthe rod the spinning device will fiy into the air, and has for itsobject the provision of improvements in this type of toy whereby thespinning of the spinner or propeller is more efiectively accomplished byreducing to a minimum drag on the propellingdevice, and also an improvedconstruction of operating or propelling member whereby the spinning ofthe propeller is more effectively accomplished as stated, and alsowhereby danger of injury to the operator is reduced to a minimum.

The invention will be described in detail hereinafter and will be foundillustrated in the accompanying drawings, in which Figure 1 is a sideview of the helicopter toy involving improvements,

Similar reference characters are used to designate corresponding partsin all the views.

The invention relates to that type of toy employing a spiral rod and aspinning device or propeller mounted thereon and given a y spinningaction by axial movement on the rod, and in the drawings the spiral rodis indicated at 1 and as shown is of a type that is originally Hat andtwisted to form the spiral, 2 indicating a hand hold at the lower I endof said rod that is shown in the drawings as a hook, but may be of anyother suitable 1931.

shape. 3 designates the spinning device that is preferably made of apiece of sheet metal and has its ends 4: tilted or canted to form apropeller. The metal of the spinning device intermediate of its ends hasa pressed downwardly rib 5 that serves to reinforce the spinning deviceand also serves to lift it from the propelling member that will behereinafter described to reduce friction in the act of operating thetoy.- 6 designates an elone0 gated opening intermediate of the ends ofthe rib 5 and in the middle of the spinning device to receive the spiralrod 1 to provide for rotation of the spinning device on the rod whenpropelled by upward movement of the op'erating device.

The propelling member or operating device for the spinning member 3consists of two partsdesignated 7 and 8, both parts being preferablymade of sheet metal, and the part 7 is formed from a blank as shown inFigure 10. In shaping the member 7 from the blank shown in Figure 10, itis first bent intermediate of its ends into a U-shape substantially onthe lines 7 The two ends of the member 7 are then bent laterallysubstantially on the line 7 to form inclined sides 9 as best shown inFigures 6, 7, and 8, and the side 10 intermediate of the inclined side9, said side 10 being concaved slightly as best shown in Figures 7 and8. 11 indicates an opening in the member 7 to receive the rod 1 when inposition thereon. 12 designates tongues extending outwardly from the Iend edges of the member 7 that engage in elongated slots 13 in themember 8 to secure the member 8 to the member 7 in assembling thedevice. The member 8 is pressed to provide an upturned flange 14: aroundits outer edge that not only rigidifies the member 8, but also serves toprevent the operators fingers from being engaged by the spinning device3 when in operation. Centrally of the member 8 is a dome-shapedprojection that extends slightly above the edge of the flange 14, and isprovided with an opening 16 to receive the rod 1, said opening beingobviously alined with the opening 11. In operating the device thedome-shaped projection 15 engages the rib 5, and this is the only art ofthe spinning device 3 that is engaged by the operating device consistingof the members 7 and 8, so that friction between the operating memberand the spinning device 5 is reduced to a minimum, and the effectivenessof the toy is thereby obviously enhanced.

What is claimed is In an aerial toy of the type employing a spiral rodand a spinning device for mount- 10 ing on the rod, a propelling memberfor the spinning device adapted to slidably engage said rod, comprisinga U-shaped member of sheet metal having an opening to receive the rod,the edges of the legs of said U-shaped 15 member inbent toprovide aconvenient hand held, tongues on the endsof said inbent portions, aplate provided With, openings to receive'sai'd tongues and secured tosaid U- shaped member, and a dome-shaped exten- 20 sion on said platehaving opening therein alined With the opening in the U-shaped memberand to also receive the spiral rod,'

said dome-shaped extension being adapted to engage the spinning devicefor propelling it.
